Abstract
The utility model relates to a spherical contact type weight reducing device which comprises a support rod, a base body, a spring and an adjusting screw, wherein the support rod is matched in the base body in a sliding manner and is extended out of the upper end of the base body; the adjusting screw is in threaded connection with the lower end of the base body; the spring is assembled between the adjusting screw and the support rod; and a universal ball protruded from the top surface of the support rod is fixedly arranged at the top of the support rod. According to the spherical contact type weight reducing device disclosed by the utility model, the friction resistance of a part is reduced by the universal ball for changing a plane contacted with the part into point contact, so that the part moves more easily during positioning action, further the part is accurately positioned and a reference hole of the part can be effectively protected from being damaged.
Description
Technical field
The utility model relates to frock clamp, specifically a kind of sphere contact type weight reducing device.
Background technology
In the fixture of machining large part (as the six-cylinder diesel engine cylinder body), conduct oneself with dignity on the impact of location components and parts in order to reduce part, and effectively protect the datum hole of part to make its injury-free (such as part impression), often adopt weight reducing device.
Existing weight reducing device as shown in Figure 1, comprise rest pad 1, cramp bar 2, matrix 3, spring 4 and adjustment screw 5, cramp bar 2 is slidably fitted in the top of matrix 3, the bottom thread of matrix 3 is connected with adjustment screw 5, be equipped with spring 4 between adjustment screw 5 and cramp bar 2, cramp bar 2 is stretching out above matrix 3 under the effect of spring 4, and rest pad 1 is fixed on the top of cramp bar 2.This weight reducing device is had relatively high expectations to the positioning datum of part, and during the location, part does not move basically, is difficult to adapt to part positioning datum hole variation occasion greatly.
Summary of the invention
The utility model provides a kind of sphere contact type weight reducing device for the problems referred to above, and this device can guarantee the part accurate positioning and can effectively protect the datum hole of part.
According to the technical solution of the utility model: a kind of sphere contact type weight reducing device, comprise cramp bar, matrix, spring and adjustment screw, described cramp bar is slidably fitted in described matrix and stretches out from the upper end of described matrix, the lower end screw thread of described matrix is connected with adjustment screw, be equipped with described spring between described adjustment screw and described cramp bar, the top of described cramp bar is fixed with the Universal caster of outstanding described cramp bar end face.
The top of described cramp bar is processed with groove, and described Universal caster is arranged in described groove.
Technique effect of the present utility model is: the plane that the utility model will contact with part changes the Universal caster of a contact into; reduced the frictional resistance of part; part is more easily moved when location action, thereby make the accurate positioning of part and can effectively protect the datum hole of part to make it injury-free.
Description of drawings
Fig. 1 is the structural representation of existing weight reducing device.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1～Fig. 2, comprise rest pad 1, cramp bar 2, matrix 3, spring 4, adjustment screw 5, Universal caster 6 etc.
As shown in Figure 2, the utility model is a kind of sphere contact type weight reducing device, comprise cramp bar 2, matrix 3, spring 4 and adjustment screw 5, cramp bar 2 is slidably fitted in matrix 3 and stretches out from the upper end of matrix 3, the lower end screw thread of matrix 3 is connected with adjustment screw 5, be equipped with spring 4 between adjustment screw 5 and cramp bar 2, adjust the elastic force of cramp bar 2 by regulating adjustment screw 5.
The top of cramp bar 2 is fixed with the Universal caster 6 of outstanding cramp bar 2 end faces.Top at cramp bar 2 is processed with groove, and Universal caster 6 is arranged in groove.
Operation principle of the present utility model is as follows: the utility model is the device that a kind of elastic force by spring 4 carries out loss of weight, part is in contact with it when being placed on Universal caster 6 and is a contact, and for rolling friction, the power F that produces during location action is easy to that part is rolled and moves along the direction of power F on Universal caster 6.
The plane that the utility model will contact with part changes the Universal caster 6 of a contact into, has reduced the frictional resistance of part, and part is more easily moved when location action, thereby makes the accurate positioning of part and can effectively protect the datum hole of part to make it injury-free.The utility model can adapt to the less demanding occasion in surface (as black skin) that there is larger variation in part positioning datum hole and part is in contact with it.
